PACKAGE CARRlER.

SPECIFICATION forming part of Letters Patent 170.358.717, dated March 1, 1887..

Application filed November 19. 1886. Serial No. 218,119. (No model.)

To on whom it may concern:

Be it known that I, SAMUEL W. BARR, of Mansfield,in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Package-Carriers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in packagecarriers; and it consists in certain features of construction and in combinations of parts,hereinafter describechand pointed out in the claims.

In the accompanying drawings, Figure l is a View in perspective of myimproved carrier. Fig. 2 is an elevation in longitudinal section. Fig. 3 is a side elevation showing one of the levers for operating the track-wires, showing also the springbuft'er. Fig. 4 is an elevation in transverse section on the line or m, Fig. 2. Fig. 5is aview in perspective of thebifurcated retaining and buffer springs. Fig. 6 is aside elevation showing a modification of the mechanism for hoisting the basket. Fig. 7 is a transverse sectional view of the parts shown in Fig. 6.

A represents the side pieces of the carrierframe, the same being arranged in pairs and connected by studs Z), on which latter arejournaled, respectively, the grooved wheels B. Suitable braces-such, for instance, as shown at Amay be added, if necessary. The wheels travel on the track-wires O, which latter, together with the mechanism for spread ing the wires to propel the carrier, have been made a subject of a prior application for United States Letters Patent, Serial No. 218,719. The sidefplates, A, have laterallyprojecting ribs or ledges, A curved longitudinally, substantially as shown. The upper surfaces of these ledges are covered with leather or other suitable material, and engage, respectively, the prongs of the bifurcated spring a, the latter being mounted. as shownin Fig. 3, 0n the end of the lever O, that operates the track-wire. The ledges present gradual inclines for the prongs of the spring to mount as the carrier approaches station receiving,

by means of which the movement of the carrier is gradually arrested by the increasing friction of the spring when mounting these inclines. The prongs of the spring are made long enough to reach some little distance past the center of the incline, by means of which they serve as retaining-springs. When the lever O is tilted to an upright position to operate the track-wires in sending the carrier, the spring is of course lifted off the incline, so that no obstruction is had in starting the carrier. The frame extends below the bottom of the lower wheels, and from thence diverges, forming jaws a, for embracing the handle D of a basket or other suitable container used in transporting packages.

E are grooved pulleys, pivoted to the frame in position substantially as shown,over which pulleys cords 6 pass, that are connected with the handle D, these cords being used for elevating and lowering the basket. These cords being applied at points on the handle D that are separated some considerable distance, the basket is kept from turning, as it would be likely to do ifa single cord is used, and the handle D is made to enter between the jaws as the basket is drawn up by means of the cords. These cords are usually united some distance from the pulleys, so that the operator handles but a single cord. A spring-catch, F, is pivoted to the frame and made to hook under the handle D when the latter is drawn up in position between the jaws. The catch is of the bell-crank-lever variety, having a laterallyprojecting arm, f, to which latter a cord, f, is attached for unfastening the handle D when the basket is to be lowered. The catch. F has a spring, G, arranged to press the hook end of the catch under the handle D, and the point of the catch has an incline, F, for engaging the handle D when the latter is being elevated, by means of which the catch is snapped back as the handle D passes.

In Figs. 6 and 7 is shown a modification in which, instead of two cords, e, abroad belt,E, is used, the latter serving the same purpose as the two cords in preventing the basket from turning while the latter is being elevated. Instead of grooved pulleys, asingle roller, 6, is used for the belts to operate on.

The springcatch F shown in Fig. 7 is sub- ""stantially the same as that shown in Fig. 4,

except that it has no incline to snap back the catch, and consequently the operator pulls on the cord or belt to draw back the catch as the handle D passes.

What I claim is- 1. The combination, with a suitable carrier, the same having wheels made to travel on the track-wires, and laterally-projecting curved ledges forming double inclines of a bifurcated spring connected with the shifting-lever of the track-Wires for engaging such incline, and made to serve the double purposeof a bumper and retaining-spring,substantially as set forth.

2. The combination, with asuitable carrier having wheels made to travel on track-wires and. arranged substantially as indicated, and

having diverging jaws connected with theframe-work of the carrier, said jaws opening downward for receiving the handle of a basket or other package-container, of suitable means, as described, for elevating the basket and cansing the handle thereof to enter between the jaws, and aspring-catch for locking the basket handle between the jaws, the parts being arranged substantially as set fort-h.

In testimony whereof I sign this specification in the presence of two witnesses.

SAMUEL W. BARR.
